Yep, it's the spare.
-
Yeah, I seem to recall something like that too... will have to dig out my pre-upgrade UM2 head when I get home, see what the spare looks like.
-
Maybe try ramping up the temperature? -
Oh, hold on. Didn't the UM2's have a spare cable in the head loom?
-
Orange and brown doesn't sound like the normal colors for the board wiring connectors... odd? Please advise if your 5V fan connector is plugged in to J34?

Mark 2 Mod and Heat resitant PLA

.... and ASA works well, too. -
Steiner Chemie sells some nice indicating silica beads on Amazon, you can get them by the kilo for a pittance. They'll change color when they've reached their absorption limit and then you can regenerate them by throwing them in the oven for a while.

UM2+ PLA clogged up and clumped around wires - recoverable?
SyntaxTerror replied to ajfl's topic in UltiMaker 3D printers
If I were you I'd disassemble the hot end, disconnect the heater and temp sensor cables for the main board, get all the plastic parts off - and then just toss it in the oven. Bake until soft and peel off the material. -
NinjaTek stuff seems rather hard to source in Europe for some reason. I was hunting for some SemiFlex myself not too long ago and finally managed to track it down at iMakr... only to have them tell me that they couldn't supply it any longer because it's going out of production. They did however instead supply me with Cheetah, which supposedly is the replacement product.

In any case, it's reasonably easy to tell whether or not you have an afflicted board, as the E2 plug is not mounted on the board (so there's nowhere to connect the second extruder stepper). It's just a matter of removing the cover and counting how many stepper motor connectors are present. 5 is good. 4, not so much.
-
Indeed, this sounds like a 2+ running 2 firmware. But if you are indeed certain that you've added the correct printer in Cura and installed the firmware for it, remove the main board cover and snap a photo of the E1 (extruder) connector wiring for us.
-
Ahh, the possibilities
-
I'll just mention here that I'm putting together a BOM for the unlucky ones, in case someone wants to do a retrofit of the missing A4988.
-
I'd start out inspecting the wire loom and connectors for possible shorts, just in case. The click would be the the main board power relay letting go.
-
I think it would be cool if we could make some sort of registry... it would be really nice to see how many people implemented this. A world map of Mark 2's or something. I'd definitely get a kick out of it.
-
Also, how's the condition of the belts? And are they tight enough?
-
Sorry, didn't mean to imply anything at all! Also, thanks a bunch for doing it in the first place - I really enjoy having a repository and being able to update things automatically. You're awesome!
-
Off-topic: that should not be the case. Have you reported this? To my eternal shame I must admit I haven't... I've got a great deal of stuff to deal with at the moment Also I'm using the @thopiekar PPA so I guess it's not really an Ultimaker maintained codebase.
-
Hmm. I have no idea about the mac version, but I'm on linux and was struggling with an issue with the configuration files as well. Cura creates a mirror structure of the resource directories inside the user's home directory. Those would be the ones any sensible user would think to edit. However, Cura also completely ignores the files there, and loads only the ones from the installation directory. So I had to play root to get mine to work. Don't know if there's something similar going on?

Hah, @foehnsturm - 113 views already. You're a regular click magnet.
-
Well, the Ultimakers are DC driven machines. You can always improvise your way around getting that DC depending on your specific constraints.
-
At least for now, anyone looking to buy an expansion board can simply throw me a PM.

It's simply a small PCB that adds additional fan drivers so the fans on the second head can be controlled individually. As the main board lacks any (unused) buffered outputs from the microcontroller, I put together a little board with the missing driver transistors. Hi, thanks for the answer. I think the question for everyone is can i still use the second extruder if i don't have that board. Or if that board is missing, is it still possible for dual extruding with 2 printheads? Thanks Yeah sure, you can just run the head #2 fans in parallel with the ones on head #1 using some Y-cables. It works just fine. You just can't turn off the #2 head entirely.
